It has no symmetry, and they have jelly like cells that transport food throughout the body. Collar Cells: fires spines that traps food. Spiky things: Protects the Sponges's body.

What phylum is most primitive?
Porifera (sponges) is considered one of the most primitive phyla because they lack true tissues and organs, and exhibit a simple body plan without symmetry.
Organisms with porous bodies belong to this phylum?
Organisms with porous bodies belong to the phylum Porifera, commonly known as sponges. Sponges are aquatic animals that lack tissue layers and have a simple body plan with numerous pores to allow water to circulate through their bodies for feeding and respiration. They are considered one of the simplest forms of multicellular animals.
What are special characteristics of porifera?
Porifera are sponges, they have no main organs or tissues. They are a loose aggregation of cells. To eat they pump water though their system and catch the particles in the water. A very basic cell structure.
What are are not part of sponges?
Sponges, belonging to the phylum Porifera, do not have true tissues or organs, which differentiates them from more complex animals. They lack a nervous system, digestive system, and circulatory system, relying instead on the flow of water through their porous bodies for nutrient intake and waste removal. Additionally, sponges do not possess specialized structures like fins, limbs, or a centralized body plan, which are found in many other animal groups.
Where do phylum porifera?
Oh, dude, phylum Porifera is like the SpongeBob SquarePants of the animal kingdom. They chill in the ocean, just hanging out, filtering water and stuff. So, yeah, you can find these guys just kicking it in the sea, living their best sponge life.
What is the kingdom of an sponge?
Sponge belongs to the kingdom Animalia. They are simple, multicellular organisms classified under the phylum Porifera. Sponges are unique for their porous bodies and lack of true tissues and organs, relying on a simple body plan to filter feed and obtain nutrients from water. They are primarily found in marine environments, although some species inhabit freshwater.
How do sponges differ from flagellate protists?
Sponges are multicellular organisms belonging to the phylum Porifera, characterized by a porous body structure and the presence of specialized cells called choanocytes that facilitate water filtration and nutrient absorption. In contrast, flagellate protists are unicellular eukaryotes that possess one or more flagella for movement and feeding, and they lack the complex tissue organization found in sponges. While sponges rely on a simple body plan for nutrient acquisition through water flow, flagellate protists actively swim to capture food particles. Thus, the key differences lie in their cellular organization, complexity, and feeding mechanisms.
What is the difference between a hydra and flatworm?
one is segmented
What type of symmetry are sponges?
an asymmetrical body plan
Which phylum of animals has a body plan that is essentially a tube within a tube?
The phylum that has a body plan that is essentially a tube within a tube is the Phylum Platyhelminthes, which includes flatworms. They have a simple body structure with a digestive tract that is a tube running from mouth to anus along the central axis of their body.
Do all animals have a symmetrical body plan?
Nope, there are some that are asymmetrical. Like sponges.
What are major characteristics of the phylum?
some of the major characteristics of the phylum are a shared body plan, embryonic development patterns, and specific molecular sequences.
